MACHINE FOR OPENINGAND PREPARING FIBER.

SPECIFICATION forming part of Letters Patent No. 365,784, dated July 5, 18 87.

Application filed July 1, 1886. Serial No. 206,763. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES N. BOURNE, of Lowell, in the county of Middlesex and State of Massachusetts, have invented anew and useful Improvement in Machines for Opening and Preparing Fiber, of which the following is a specification.

My invention relates to machines for opening and preparing cotton, wool, and similar fibers; and it consists in certain new and useful combinations and arrangements of the several parts of such machines, substantially as hereinafter described and claimed.

In the drawings, Figure 1 is aside elevation of a waste-opener constructed according to my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a rear end elevationof the same. Fig. 4. is a vertical longitudinal section of Figs. 2 and 3 on the lines A B and O D. Fig. 5 is a top view of the divided feed trough or plate. Fig. 6 is an enlarged view of the end of the feed-apron, roller I, and one section of the divided feed trough or plate, with the co-operating parts. Fig. 7 is an end view of the section of the divided feedtrough. Fig. 8 is a side view of a portion of the bar supporting the divided feed-trough.

ll/I is the frame of the machine, which supports and partially incases the working parts.

F is the feed-apron of the opener, constructed of slats in the usual manner, passing around rolls f f.

G is the main opener or picker-cylinder, which separates the cotton or other waste fiber and prepares it for use. This cylinder is adapted to be used principally for picking apart what is technically known as cotton waste, and is therefore constructed with straight spines or teeth set around its periphcry, as shown.

I is a grooved feed-roller, which feeds the waste to the main cylinder, in conjunction with a curved plate, z, beneath it, the fiber being carried through between the latter and the feed-roller I by its revolution.

The fibers of the cotton waste are very short from having been repeatedly worked over previously, and the feed-roller I and platei have a nip or hold upon the fiber quite up to the spines of cylinder G and insure the complete separation of the fibers. As the waste is full of small knots and bunches of twisted fibers, when the curved plate 2 is made in one piece across the entire breadth of the maehine,t-hese knots and bunches, passing between the plate 2' and roll I, separate them, so as to allow the spines of the main cylinder to snatch and draw out other and thinner masses of fiber without properly picking apart and separating it. To overcome this difficulty, I divide or separate the plate 2' transversely of it into two or more sections, 1', and pivot these sections upon the pivot 19, which is a rod passing horizontally and transversely across the frame of the ma chine, from side to side, in which it is fixed.

R 'is a supplemental feed-roller revolving in the direction indicated by the arrow in Fig.6, and intended to receive the waste fiber from the feed-apron F and convey it to the divided feed trough or platter and the feed-roller I over its upper side. This roller is made with a smooth surface and is interposed between the feed-apron F and the feed-roller I,

because it is found that if it be attempted to feed the cotton waste directly from the feedapron upon the trough i and to feed-roll I a considerable proportion of the shorter fibers are drawn downward and backward by the motion of the feed apron and carried through between it and the trough i and dropped beneath the machine. The feed-apron being slatted, it is impossible to bring any part of the plated near enough to the apron-surface to prevent this. By the use of the smooth roll R, however, revolving as described, the tendency of the feed-apron F to draw the fibers around underneath it is overcome when they meet the surface of the roller, drawing them in the opposite direction, and they are carried forward and delivered between plate 1' and feed-roller I. Vhen they arrive at the opposite side of roller R from the feedapron F,

the fibers are prevented from being drawn down between plate and the roller, because, the roller being smooth,the rear edge of the trough or plate i is carried back very closely to the surface of it and forms a scraper or doffer to clear off the fibers from its surface when they are drawn in between trough iand feed-roll I by the longer fibers which are passing in that direction; but in order to have the transversely-divided trough or plate i operate, as before described,in conjunction with feed-roll I, and at the same time as a doffer for roll R, and have each section or division z" of said plate yield separately to larger or smaller lumps or knots of fiber and still act as such a doffer of its portion of roll R, I am obliged to so hang or pivot each section of the trough or plate that as it yields to the knots or lumps of fiber passing between it and feedroll I it will move away from the path of the spines of the main cylinder G on its side nearest them, and will also move in a path approximating to the curvature of roller B on its edge nearest to the latter; and it is in giving this movement to the sections of the divided trough or plate that my invention consists. To accomplish this I place the pivot 19, on which the sections i of plate ii are hung,upon the op posite side of roller R from the feed-roll Land connect each section with its pivot by a curved arm, a, passing underneath roller It. When any section z" of the trough or platei yields to knots or bunches of fiber passing between it and feed-roll I, its outer edge swings away from the path of the spines on the main cylinder, and its edge next to roller R traverses a curved path approximating so nearly to the surface of the latter that it continues to act as a doffer upon that portion of the roll andprevents the fibers from passing between it and such section of trough or plate i. In order to provide for the proper tension of each section t" of trough or plate 11, without allowing it to come into actual contact with feed-roller I, (which would wear outthe feed-roller or the section,) I secure a bar, I), (see Fig. 6,) transverse] y across the machine underneath the trough or plate 1 and attach a bolt, 12', by a transverse pivot-,b", to an ear, b formed on the lower side of such section. I then slip spring Sover thelooltband pass the lower and free end of the bolt through a hole in the bar b and screw anut, I), onto a thread provided for it upon the lower end of the bolt beneath bar I).

' By screwing the nut I) up or down, the section can then be adjusted to the proper distance from feed-roll I, and the spring S will give the requisite grip or compression upon the section against the fiber passing over such section.

A jam-nut, 12 may be used upon bolt 1), to keep nut b in place, if desired. After the fiber has passed the main cylinder G, it is re ceived upon the apron F which passes around rollersf f", and carried along beneath rollers R R out of the machine.

The main cylinder G is driven by a pulley, 9, upon its shaft. The tight and loose pulley 1? receives motion from pulley 9 upon the other end of the same shaft, and drives a sleeve on stud s, which has attached to it pulley p. The latter. is belted by a cross-belt to pulley p on shaft .s The latter has on its ends worms which drive worm-gears on shafts s and s, .9 being the shaft on which apron-roll f z is mounted, and s beingthe shaft carrying feedroll I. From the latter, by trains of gears 17 p, the roller It and feed-apron roll f are driven, as shown. Pulley p on shaft s is belted to pulley p on the shaft of roller R Asthese driving-belts and gears are of ordinary construction and form no part of myinvention, it is not necessary to describe them further.

- WhatI claim as new and of myinvention is- 1. The combination of feed-apron F, pickercylinder G, and feed-roller Iwith 'feedroller R,intermediate the latter and the feed-apron,

and the divided trough or plate 1', formed of two or more sections, 6, each projecting under roll I, and having its rearend in proximity to roller R, and means, substantially as described, for supporting said sections and permitting the same to yield in a direction away from the path of the picker-cylinder and in a path substantially coinciding with the surface of roller It, substantially as and for the purpose set forth.

2. The combination of feed-apron F, pickercylinderG, and feed-roller I with roller R, in-

termediate the apron and roller I, and the di-' vided trough or plate 13, formed of two or more sections, i, each projecting under roller I, and having its rear end in proximity to roller R, and each having a curved arm, t pivoted upon the side of roller R opposite from roller I, and means for pressing said sections toward roller I, substantially as described.

3. The combination of main picker-cylinder G, feed-roll I, the divided trough or plate 1', formed of two or more sections, i, hung upon pivots on the opposite side of the feed-roll from the main cylinder, bolts 12 b, pivoted to said sections, springs S, bar b, andnuts If, substantially as described.
